AEROPLANE.

Specification of Letters Patent. Patented Feb. llll, I919.

Application filed December 7, 1916. Serial No. 135,551.

templates the novel utilization of such space as a muffler, by placing it in communication with the exhaust manifold of a forwardly installed motor.

In the drawing Figure 1 is a plan view of an aeroplane having my improvements, and

Fig. 2 is an enlarged detail view of the exhaust muflling means.

The drawin shows a conventional form of aeroplane, llaving supporting surface 1 and fuselage 2. The forward portion of the fuselage may contain the motor 3 and the rear portion of the fuselage, which is inclosed behind the cockpit 3, may afford the space to which the engine exhaust is conducted, as by exhaust pipe 4.

The rearward inclosed-portion of thefuselage, which may contain a muffler as 5, by

reason of its dimensions, permits the expansion of the exhaust gases therein prior to their efilux from said chamber to the atmosphere.

While not restricted to any particular means of exit from the expansion chamber, I have shown an outlet 15 leading from said chamber to the atmosphere. A baflie 14 may also be employed to direct said exhaust gases to said outlet 15.

I claim 1. In an aeroplane, in combination, a fuselage, an engine located in the forward portion thereof, a chamber entirely inclosed .within the rearward portion of said fuselage, and means for conducting the exhaust products from said engine to said chamber.

2. In an aeroplane, in combination, a fuselage, an engine located in the forward portion thereof, a mufiler entirely inclosed within the rearward portion of said fuselage, and means for conducting exhaust products from said engine to said mufiler.

3. In an aeroplane, in combination, a fuse- .lage, an engine located therein near its forward end, a muflier chamber entirely inclosed within said fuselage, an intermediate cockpit, and means for conducting exhaust products from said engine to said muifier chamber.

Signed. at the boron h of Manhattan, in the city, county, and tate of New York, this 6th day of December, A. D. 1916.
